Definitions
- the invention relates to a top pin assembly for a swinging door, and more particularly, to a top pin assembly with a hold open device maintaining the door in an open position.
- Traffic doors are typically used in commercial establishments to allow two-way traffic through a doorway. Such doors may be used in a variety of such establishments including supermarkets, restaurants, retail stores, hospitals, walk-in coolers, etc.
- the doors may be provided singly or in pairs, and mount to a door frame by hinges which allow the doors to freely swing in opposite directions, i.e. both inwardly into a room and outwardly from the room. In a commercial establishment, this allows employees to freely move between two adjacent rooms merely by pushing on the freely, swingable doors wherein the doors automatically return to the closed position without any further action from the employee, which thereby facilitates the traffic flow of employees from room to room.
- Such traffic doors also have a hinge arrangement connecting each door to a door frame which allows the doors to swing in opposite directions, but also gently closes or returns the door to a closed or “rest” position blocking the doorway.
- a hinge assembly is disclosed in U.S. Pat. Nos. 3,160,913 and 3,289,244, which patents were obtained by the assignee of the present invention. The disclosures of these patents are incorporated herein by reference in their entirety.
- These hinge assemblies operate to close the door without the need for a spring arrangement that would generate a spring force to bias the doors to a closed position. Rather, the hinge assemblies disclosed in these patents use a roller assembly which generates a closing action on the doors by gravity acting upon the door itself.
- the invention relates to an improved door assembly which positively restrains the door in a normally closed position.
- the improved door assembly preferably includes an improved top pin assembly which not only provides positive restraining of the door in the closed position, but also allows for positive restraining of the door in at least two fully open positions, preferably oriented at right angles relative to this closed position.
- the top pin assembly provides integral restraining of the door, such that separate external restraining devices are not required to maintain the door in the open position. This allows for free traffic flow through the doorway for individuals who may be carrying bulky or heavy loads, or pushing carts.
- the top pin hinge assembly allows the door to simply be opened to the fully open position wherein the top pin assembly automatically holds the door in this position until the door is manually pushed in the direction of closing which then causes the door assembly to automatically return to the fully closed position.
- FIG. 1 is a perspective view of a door with a top pin door assembly having a hold open device.

- the doorway 14 typically extends through a partition wall such as the wall of a building or the wall of a cooler.
- the doorway 14 is defined by a bottom threshold or floor, upright door jambs 16 and a crosswise header 18 .
- the jambs 16 and the header 18 typically have a side-to-side width which is defined by the thickness of the partition wall and has a conventional rectangular shape.
- the top pin assembly 12 connects to the inside faces of one of the jambs 16 and the header 18 , and to the door 11 , wherein the door 11 is pivotally connected to such top pin assembly 12 to permit swinging movement of the door 11 in opposite swinging directions.
- the top pin assembly 12 permits bidirectional swinging movement of the door 11 between the closed position of FIG. 1 and a first open position of FIG. 2 wherein the door is at a right, 90 degree angle relative to the closed position.
- the door 11 includes the top pin assembly 12 in the upper corner thereof which cooperates with the door frame to effect a self-centering of the door 11 so as to generally be centered within the doorway 14 widthwise of the partition wall in the closed position of FIG. 1 .
- the top pin assembly 12 comprises a box-like cover (not illustrated) which provides selective access to the top pin assembly 12 so that it is accessible from the side as seen in FIG. 1 .
- the top pin assembly 12 not only biases the door 11 to the closed position of FIG. 1 , but also includes a hold open feature which holds the door 11 open in either the first open position of FIG. 2 or a second open position wherein the door is oriented 180° relative to the first open position of FIG. 2 . In this second open position, the door is still oriented at the right, 90° angle relative to the closed position ( FIG. 1 ) after the door 11 has been swung in the opposite direction.
- the top pin assembly 12 first comprises a hinge bracket 20 which comprises a horizontal leg 21 and a vertical leg 22 which are respectively secured to the header 18 and jam 16 by suitable fasteners 23 , which are preferably screws.
- the hinge bracket 20 includes a downwardly extending, fixed hinge post or pin 25 which is preferably welded to the horizontal bracket leg 21 .
- the bottom or terminal end of the hinge pin 25 includes a pair of diametrically opposed rollers 27 located on diametrically opposite sides of the pin 25 .
- the rollers 27 are rotatably supported upon a shaft 28 which extends diametrically through the end of the pin 25 , wherein the free ends of the shaft 28 each support a respective one of the rollers 27 thereon.
- the pin 25 thereby extends downwardly in a vertical orientation and rotatably supports the rollers 27 thereon.
- the hinge bracket 20 and hinge pin 25 thereby remain in stationary fixed positions during use.
- the remaining components of the top pin assembly 12 described below are rotatably suspended from the top pin 25 by the rollers 27 and are fastened to the door, which thereby allows the door 11 to swing between the open and closed positions.
- the top pin assembly 12 further comprises base brackets 30 , one of which is located on one side of the door and includes a top flange 31 on which a generally C-shaped housing 33 is rigidly affixed.
- a similar base bracket 30 is also provided on the opposite side of the door 11 wherein the two base brackets 30 align with each other and are secured to the door 11 by a pair of bolts 30 A which pass entirely through the door 11 , engage both of the base brackets 30 , and effectively clamp the door 11 between the two base brackets 30 .
- a respective cover is provided so as to overlie each side of the door 11 and enclose this hardware, including the base brackets 30 , during use.
- the C-shaped housing 33 extends through the entirety of the door 11 and is fastened to each of the base brackets 30 , such as by welding, so that the entire assembly is secured to the door 11 by the aforementioned bolts 30 A.
- the base bracket 30 includes a pair of fastener blocks 34 which allow for affixing of the cover thereto.
- the housing 33 comprises a bottom wall 34 which extends horizontally through a notch 36 ( FIG. 1 ) which is formed in the upper corner of the door.
- the bottom wall 34 is welded to the base brackets 30 as mentioned above.
- the housing 33 further comprises vertical side walls 37 which in turn are bent inwardly at their tops to define a first housing leg 38 and a second housing leg 39 . These housing legs 38 and 39 are spaced apart from each other to define a gap through which the support pin 25 may extend vertically as seen in FIGS. 1 and 2 .
- the top pin assembly 12 further comprises a top support plate 40 which has opposite first and second ends 41 and 42 .
- a first plate end 41 (as seen in FIGS. 3A , 3 B, 4 and 5 ) is substantially flat and includes a pair of bore holes 43 for fixed securement of the support plate 40 to the main housing 34 .
- the first plate end 40 is disposed beneath the housing flange 38 and is secured thereto by a pair of threaded bolts or other fasteners 44 as seen in FIG. 1 .
- the rollers 27 engage the support plate 40 , the weight of the door is carried on the plate ends 41 and 42 through the housing flanges 38 and 39 .
- the opposite plate end 42 is formed with a structure rigidifying downwardly depending leg 46 wherein the second plate end 42 in turn is disposed below in load-bearing relation with the housing flange 39 as seen in FIGS. 1 and 2 .
- the plate 40 is formed with a central bore 49 ( FIGS. 3A and 3B ) to allow the hinge post 25 to extend vertically therethrough.
- the central portion of the plate 40 includes two V-shaped centering notches 50 in which the rollers 27 seat when in the position of FIG. 1 .
- the support plate 40 is pre-attached to the hinge pin 25 by inserting the plate 40 over the free end of the pin 25 prior to installation of the rollers. After this pre-assembly step, the rollers 27 are then affixed to the bottom terminal end of the hinge pin 25 by installation of the rollers 27 in the shaft 28 . Once the rollers 27 are installed in this manner, the support plate 40 is no longer removable from the pin 25 .
- the housing 34 has already been installed on the door 11 through the base brackets 30 and the associated bolts 30 A.
- the aforementioned gap between the housing flanges 38 and 39 then allows the door to be lifted and shifted sidewardly until the support plate 40 , previously attached to the pin 25 , is inserted below the flanges 38 and 39 and the door 11 is pre-hung from the support plate 40 and the engaged hinge pin 25 .
- the door 11 is still in a loose condition, but is affixed to the support plate 40 by installation of the fasteners 44 which thereby prevents the door 11 from being removed from the hinge pin 25 and the associated hinge bracket 20 .
- the hinge bracket 20 has already been installed on the door frame, such that the assembly of the door 11 and its suspension from the support plate 40 thereby positions the door 11 within the doorway.
- a bracket is also provided at the bottom corner of the door to fix the location of the door corner relative to the door frame. In this manner, the door 11 is now functional or swingable between the open and closed positions described below.
- the rollers 27 roll along the bottom side of the centering notch 50 which allows the door to swing openly.
- the weight of the door and the inclined surfaces of the centering notch 50 also perform a biasing or centering action on the door 11 to return the door 11 to the normally closed position of FIG. 1 .
- FIGS. 6 and 7 illustrate the support plate 40 in the normally closed orientation with the rollers 27 seated within the centering notches 50 .
- the support plate 40 also includes a pair of diametrically opposite restraining slots 52 which extend radially outwardly from the center bore 49 and are oriented diametrically opposite to each other as seen in FIG. 33 .
- the restraining slots 52 are oriented preferably at 90° or right angles relative to the centering notches 50 . While the restraining slots 52 extend entirely through the support plate 40 as seen in FIGS. 3A and FIG.
- the support plate 40 also may be modified somewhat so that the restraining slots 52 are shallower and only extend partway through the thickness of the plate 40 to define arcuate recesses 52 A.
- the U-shaped edge 53 of each slot 52 is beveled or angled to have an angled and arcuate incline and generally conform to the outside diameter of the rollers 27 .
- the shallower recesses 52 A also have a similar arcuate shape to conform to the outside diameter of the roller 27 and thereby positively seat the roller 27 within such slots 52 or 52 A.
- FIG. 8 and 9 illustrate the rollers 27 when they seat within the slots 52 which occurs when the plate 40 and the associated door 11 have been rotated 90° to either one of the open positions.
- FIG. 2 illustrates the door 11 in the first open position
- FIG. 9 illustrates the plate 40 rotated to the other open position with the plate 40 oriented 180° relative to the orientation of the plate 40 in FIG. 2 .
- These define the preferred first and second open positions for the door 11 which each are preferably oriented at a right angle relative to the normally closed position of FIG. 1 .
- rollers 27 Positive seating of the rollers 27 within the restraining slots 52 occurs as the rollers 27 essentially seat vertically within the slots 52 .
- the rollers 27 roll upon the flat bottom surface of the support plate 40 , they eventually will roll up the inclined perimeter edges 53 of the slots 52 wherein the door 11 displaces vertically downwardly as the rollers 27 align with the slots 52 and the slots 52 fall downwardly onto the rollers 27 .
- the rollers 27 Upon closing of the door, the rollers 27 reverse directions and the slots 52 or 52 A roll up along the rollers 27 which causes the door 11 to shift vertically upwardly until the door 11 returns to the closed position, wherein the rollers 27 then seat within the centering notches 50 during which time, the door again shifts downwardly.
- this invention requires that the door 11 be vertically shiftable to a limited extent.
- the support plate 40 can be provided with both a positive centering feature maintaining the door 11 in a normally closed position, and a hold open feature which restrains the door in the fully open position due to the provision of the restraining slots 52 .
- This allows the door 11 to be simply maintained through its own top pin assembly 12 in either of two open positions. This does not require any additional separate devices to restrain the door 11 and simply occurs as the door 11 is opened to the fully open position, at which time the rollers 27 vertically engage the slots 52 or 52 A.
- the engagement of the rollers 27 with the slots 52 or 52 A requires a relatively low amount of force to disengage these components and return the door 11 to the closed position, but such resistance to closing is not significant and can be readily overcome by manual pushing of the door 11 towards the closed position.
Abstract
Description
- This application claims priority of U.S. Provisional Patent Application No. 61/463,984, filed Feb. 25, 2011, the disclosure of which is incorporated herein by reference in its entirety.
- The invention relates to a top pin assembly for a swinging door, and more particularly, to a top pin assembly with a hold open device maintaining the door in an open position.
- Traffic doors are typically used in commercial establishments to allow two-way traffic through a doorway. Such doors may be used in a variety of such establishments including supermarkets, restaurants, retail stores, hospitals, walk-in coolers, etc.
- The doors may be provided singly or in pairs, and mount to a door frame by hinges which allow the doors to freely swing in opposite directions, i.e. both inwardly into a room and outwardly from the room. In a commercial establishment, this allows employees to freely move between two adjacent rooms merely by pushing on the freely, swingable doors wherein the doors automatically return to the closed position without any further action from the employee, which thereby facilitates the traffic flow of employees from room to room.
- More particularly, such traffic doors also have a hinge arrangement connecting each door to a door frame which allows the doors to swing in opposite directions, but also gently closes or returns the door to a closed or “rest” position blocking the doorway. Examples of such a hinge assembly are disclosed in U.S. Pat. Nos. 3,160,913 and 3,289,244, which patents were obtained by the assignee of the present invention. The disclosures of these patents are incorporated herein by reference in their entirety. These hinge assemblies operate to close the door without the need for a spring arrangement that would generate a spring force to bias the doors to a closed position. Rather, the hinge assemblies disclosed in these patents use a roller assembly which generates a closing action on the doors by gravity acting upon the door itself.
- A specific example of such traffic doors is the family of doors sold by the present assignee, namely Eliason Corporation, under its EASY SWING® trademark.
- It is an object of the invention to provide an improved door assembly of this general type which incorporates an improved hinge assembly which serves to releasably restrain the door in both a closed position, and in open positions preferably oriented at right angles relative to the closed position.
- The invention relates to an improved door assembly which positively restrains the door in a normally closed position. The improved door assembly preferably includes an improved top pin assembly which not only provides positive restraining of the door in the closed position, but also allows for positive restraining of the door in at least two fully open positions, preferably oriented at right angles relative to this closed position. In this manner, the top pin assembly provides integral restraining of the door, such that separate external restraining devices are not required to maintain the door in the open position. This allows for free traffic flow through the doorway for individuals who may be carrying bulky or heavy loads, or pushing carts. Where the traffic volume is high, at least on a temporary basis, the top pin hinge assembly allows the door to simply be opened to the fully open position wherein the top pin assembly automatically holds the door in this position until the door is manually pushed in the direction of closing which then causes the door assembly to automatically return to the fully closed position.
- Other objects and purposes of the invention, and variations thereof, will be apparent upon reading the following specification and inspecting the accompanying drawings.

- Referring to
FIGS. 1 and 2 , an improveddoor assembly 10 comprises a panel-like door 11 which is connectable by bracketry, namely atop pin assembly 12 and a lower bracket, which mount to theframe 13 of adoorway 14. More particularly, thedoorway 14 typically extends through a partition wall such as the wall of a building or the wall of a cooler. Thedoorway 14 is defined by a bottom threshold or floor,upright door jambs 16 and acrosswise header 18. Thejambs 16 and theheader 18 typically have a side-to-side width which is defined by the thickness of the partition wall and has a conventional rectangular shape. - As seen in
FIG. 1 , thetop pin assembly 12 connects to the inside faces of one of thejambs 16 and theheader 18, and to thedoor 11, wherein thedoor 11 is pivotally connected to suchtop pin assembly 12 to permit swinging movement of thedoor 11 in opposite swinging directions. As such, thetop pin assembly 12 permits bidirectional swinging movement of thedoor 11 between the closed position ofFIG. 1 and a first open position ofFIG. 2 wherein the door is at a right, 90 degree angle relative to the closed position. - As seen in
FIG. 1 , thedoor 11 includes thetop pin assembly 12 in the upper corner thereof which cooperates with the door frame to effect a self-centering of thedoor 11 so as to generally be centered within thedoorway 14 widthwise of the partition wall in the closed position ofFIG. 1 . Thetop pin assembly 12 comprises a box-like cover (not illustrated) which provides selective access to thetop pin assembly 12 so that it is accessible from the side as seen inFIG. 1 . - The
top pin assembly 12 not only biases thedoor 11 to the closed position ofFIG. 1 , but also includes a hold open feature which holds thedoor 11 open in either the first open position ofFIG. 2 or a second open position wherein the door is oriented 180° relative to the first open position ofFIG. 2 . In this second open position, the door is still oriented at the right, 90° angle relative to the closed position (FIG. 1 ) after thedoor 11 has been swung in the opposite direction. - More particularly as to the
top pin assembly 12, thetop pin assembly 12 first comprises ahinge bracket 20 which comprises ahorizontal leg 21 and avertical leg 22 which are respectively secured to theheader 18 andjam 16 bysuitable fasteners 23, which are preferably screws. Thehinge bracket 20 includes a downwardly extending, fixed hinge post orpin 25 which is preferably welded to thehorizontal bracket leg 21. The bottom or terminal end of thehinge pin 25 includes a pair of diametrically opposedrollers 27 located on diametrically opposite sides of thepin 25. Therollers 27 are rotatably supported upon ashaft 28 which extends diametrically through the end of thepin 25, wherein the free ends of theshaft 28 each support a respective one of therollers 27 thereon. Thepin 25 thereby extends downwardly in a vertical orientation and rotatably supports therollers 27 thereon. Thehinge bracket 20 and hingepin 25 thereby remain in stationary fixed positions during use. As will be described hereinafter, the remaining components of thetop pin assembly 12 described below are rotatably suspended from thetop pin 25 by therollers 27 and are fastened to the door, which thereby allows thedoor 11 to swing between the open and closed positions. - To support the
door 11 upon therollers 27, thetop pin assembly 12 further comprisesbase brackets 30, one of which is located on one side of the door and includes atop flange 31 on which a generally C-shaped housing 33 is rigidly affixed. Asimilar base bracket 30 is also provided on the opposite side of thedoor 11 wherein the twobase brackets 30 align with each other and are secured to thedoor 11 by a pair ofbolts 30A which pass entirely through thedoor 11, engage both of thebase brackets 30, and effectively clamp thedoor 11 between the twobase brackets 30. A respective cover is provided so as to overlie each side of thedoor 11 and enclose this hardware, including thebase brackets 30, during use. The C-shaped housing 33 extends through the entirety of thedoor 11 and is fastened to each of thebase brackets 30, such as by welding, so that the entire assembly is secured to thedoor 11 by theaforementioned bolts 30A. Thebase bracket 30 includes a pair offastener blocks 34 which allow for affixing of the cover thereto. - More particularly, the
housing 33 comprises abottom wall 34 which extends horizontally through a notch 36 (FIG. 1 ) which is formed in the upper corner of the door. Thebottom wall 34 is welded to thebase brackets 30 as mentioned above. Thehousing 33 further comprisesvertical side walls 37 which in turn are bent inwardly at their tops to define afirst housing leg 38 and asecond housing leg 39. Thesehousing legs support pin 25 may extend vertically as seen inFIGS. 1 and 2 . - To mount the
door 11 to thepin 25, thetop pin assembly 12 further comprises atop support plate 40 which has opposite first and second ends 41 and 42. A first plate end 41 (as seen inFIGS. 3A , 3B, 4 and 5) is substantially flat and includes a pair of bore holes 43 for fixed securement of thesupport plate 40 to themain housing 34. In this regard, thefirst plate end 40 is disposed beneath thehousing flange 38 and is secured thereto by a pair of threaded bolts orother fasteners 44 as seen inFIG. 1 . As such, when therollers 27 engage thesupport plate 40, the weight of the door is carried on the plate ends 41 and 42 through thehousing flanges opposite plate end 42 is formed with a structure rigidifying downwardly dependingleg 46 wherein thesecond plate end 42 in turn is disposed below in load-bearing relation with thehousing flange 39 as seen inFIGS. 1 and 2 . Hence, when thesupport plate 40 is fastened in place by thebolts 44, all of the load of the door is carried by thetop pin 25 through the engagement of therollers 27 with theplate 40. - The
plate 40 is formed with a central bore 49 (FIGS. 3A and 3B ) to allow thehinge post 25 to extend vertically therethrough. The central portion of theplate 40 includes two V-shaped centeringnotches 50 in which therollers 27 seat when in the position ofFIG. 1 . Preferably, thesupport plate 40 is pre-attached to thehinge pin 25 by inserting theplate 40 over the free end of thepin 25 prior to installation of the rollers. After this pre-assembly step, therollers 27 are then affixed to the bottom terminal end of thehinge pin 25 by installation of therollers 27 in theshaft 28. Once therollers 27 are installed in this manner, thesupport plate 40 is no longer removable from thepin 25. - During assembly of the door, the
housing 34 has already been installed on thedoor 11 through thebase brackets 30 and the associatedbolts 30A. The aforementioned gap between thehousing flanges support plate 40, previously attached to thepin 25, is inserted below theflanges door 11 is pre-hung from thesupport plate 40 and the engagedhinge pin 25. Thedoor 11 is still in a loose condition, but is affixed to thesupport plate 40 by installation of thefasteners 44 which thereby prevents thedoor 11 from being removed from thehinge pin 25 and the associatedhinge bracket 20. Notably, thehinge bracket 20 has already been installed on the door frame, such that the assembly of thedoor 11 and its suspension from thesupport plate 40 thereby positions thedoor 11 within the doorway. A bracket is also provided at the bottom corner of the door to fix the location of the door corner relative to the door frame. In this manner, thedoor 11 is now functional or swingable between the open and closed positions described below. - During rotation of the door, the
rollers 27 roll along the bottom side of the centeringnotch 50 which allows the door to swing openly. However, the weight of the door and the inclined surfaces of the centeringnotch 50 also perform a biasing or centering action on thedoor 11 to return thedoor 11 to the normally closed position ofFIG. 1 . -
FIGS. 6 and 7 illustrate thesupport plate 40 in the normally closed orientation with therollers 27 seated within the centeringnotches 50. To define the hold open feature, thesupport plate 40 also includes a pair of diametricallyopposite restraining slots 52 which extend radially outwardly from the center bore 49 and are oriented diametrically opposite to each other as seen inFIG. 33 . The restrainingslots 52 are oriented preferably at 90° or right angles relative to the centeringnotches 50. While the restrainingslots 52 extend entirely through thesupport plate 40 as seen inFIGS. 3A andFIG. 7 , thesupport plate 40 also may be modified somewhat so that the restrainingslots 52 are shallower and only extend partway through the thickness of theplate 40 to definearcuate recesses 52A. For theslots 52 ofFIGS. 3A andFIG. 7 , theU-shaped edge 53 of eachslot 52 is beveled or angled to have an angled and arcuate incline and generally conform to the outside diameter of therollers 27. As seen inFIG. 4 , theshallower recesses 52A also have a similar arcuate shape to conform to the outside diameter of theroller 27 and thereby positively seat theroller 27 withinsuch slots FIGS. 8 and 9 illustrate therollers 27 when they seat within theslots 52 which occurs when theplate 40 and the associateddoor 11 have been rotated 90° to either one of the open positions.FIG. 2 illustrates thedoor 11 in the first open position, whileFIG. 9 illustrates theplate 40 rotated to the other open position with theplate 40 oriented 180° relative to the orientation of theplate 40 inFIG. 2 . These define the preferred first and second open positions for thedoor 11 which each are preferably oriented at a right angle relative to the normally closed position ofFIG. 1 . - Positive seating of the
rollers 27 within the restrainingslots 52 occurs as therollers 27 essentially seat vertically within theslots 52. In this regard, as therollers 27 roll upon the flat bottom surface of thesupport plate 40, they eventually will roll up the inclined perimeter edges 53 of theslots 52 wherein thedoor 11 displaces vertically downwardly as therollers 27 align with theslots 52 and theslots 52 fall downwardly onto therollers 27. Upon closing of the door, therollers 27 reverse directions and theslots rollers 27 which causes thedoor 11 to shift vertically upwardly until thedoor 11 returns to the closed position, wherein therollers 27 then seat within the centeringnotches 50 during which time, the door again shifts downwardly. Thus, this invention requires that thedoor 11 be vertically shiftable to a limited extent. - In this manner, the
support plate 40 can be provided with both a positive centering feature maintaining thedoor 11 in a normally closed position, and a hold open feature which restrains the door in the fully open position due to the provision of the restrainingslots 52. This allows thedoor 11 to be simply maintained through its owntop pin assembly 12 in either of two open positions. This does not require any additional separate devices to restrain thedoor 11 and simply occurs as thedoor 11 is opened to the fully open position, at which time therollers 27 vertically engage theslots rollers 27 with theslots door 11 to the closed position, but such resistance to closing is not significant and can be readily overcome by manual pushing of thedoor 11 towards the closed position. - Although particular preferred embodiments of the invention have been disclosed in detail for illustrative purposes, it will be recognized that variations or modifications of the disclosed apparatus, including the rearrangement of parts, lie within the scope of the present invention.
